I don't like Leighton Denny's accent - not sure where he comes from. Used to like the accent of the young lady who did the Travelon show. Sad I know - but put it down to my age!!!
It's the tone and pitch of some peoples voices rather than the accent - AY is the classic example at QVC.
I like the Welsh accent but BBC presenter Alex Jones drives me NUTS!
I agree with you on both of these - though to be fair I'm not sure if it's Leighton's accent I dislike, or the man himself - he just seems so full of himself. I can only watch him on mute.
